SPECIFICATION forming part of Letters Patent No. 454,910, dated June 30,1891.

Application filed November 1, 1890. Serial No. 370,094. (No model.)

To all whom/ii may concern:

Be it known that I, LAZARD KAHN, of Hamilton, Butler county, Ohio, haveinvented certain new and useful Improvements in Gas- Burners, (Case 3,)of which the following is a specification.

This invention pertains to improvements in the large heavy gas-burnersgenerally employed in connection with stoves or other heating or cookingapparatus, the weight and conditions of use of the burners being suchthat it becomes important to provide the burners with some rigid supportindependent of the pipe which supplies them with gas, andin which alsoit is desirable to provide for the ready opening of theburner.

My improvements will be readily understood from the followingdescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is a plan of a burner embodying my present improvements;Fig. 2, a side elevation of the same; Fig. 3, a vertical section of thesame upon a larger scale; Fig. at, abottom view of an exemplifyinggas-stove shown as provided with four of my improved burners, and Fig. 5a front elevation and Vertical section of the same. i

In the drawings, A indicates the shallow cup-shaped circular body of theburner; B, the upper annular rini thereof; 0, a series of notches inthis rim; D, a gas-inlet leading to the interior of the body; E, a pipeattaching to the body of the burner at such inlet for the'supply of thegas; F, a disk seating down upon the rim B, the notches 0 thus formingjet-holes at the periphery of the burner; G, an upwardly-turned rim uponthe disk F, concentrically disposed inwardly from the periphery of thedisk; H, a series of notches in this rim of the disk similar to thenotches O in the body of the burner; J, a cap-piece seating upon thedisk-rim G and forming the top of the burner and causing the notches Hto form an inner upper annular series of j etholes for the burner; K, anaxially-disposed bolt securing the cap-piece to the body of the burnerand clamping the disk F between them; L, a centrically-walled centralopening down through the cap -piece; M, a similar opening through thebottom of the body of the burner, the walls of the openings L and Mjoining to form a central vertical tube through the burner; N, bridgesacross the openings L and M to receive the bolt K, which; when thecentral tube is employed, finds itself disposed in the axis of the tube;0, a'series of notches at the juncture of the walls of the openings Land H, these notches forming a series of' jet-holes leading from withinthe chamber of the burner to within the central vertical tube at or nearthe base of the tube; and P, an arm integrally with or rigidly united tothe disk F and projecting radially therefrom and provided at its outerend with attaching features, exemplified as a slot to receive a bolt; Q,the usual gas-pipe, from which anumber of burners on the stove taketheir supply; R, the usual mixers on the outer ends of theburner-pipesE; S, the usual gascocks to shut off the gas to the severalburners; T, the top of the stove, to which the burners are applied, andU the cooking-holes in the top of the stove.

Assume that the burner is to be used in connection with a cooking-stoveand that sev-' eral of the burners are employed inthe stovesay afour-hole stove'and that the gas-supply pipes cannot come to all theburners in a uniform direction, and that the points of support of theburners vary in direction from the centers of the several burners. Insuch case the arms F may be bolted under the top plate of the stove, thearms projecting in any expedient direction from the centers of theburners, the centers of the burners being, as usual, disposed concentricto the top holes of the stove. The arms of the several burners mayproject in different directions, according as the points of attachmentdetermine. The bolt K may then be loosened and the body of the burnerrotated upon a vertical axis till the supply-pipe projects in thedesired direction, wh ereupon the bolt. may be again tightened. The armP and supply-pipe E may thus be adjusted to any desired angle withreference to each other, thus adapting the burner to any predeterminedcondition of direction of supply-pipe and attaching-point with referenceto each other and to the center often found in practice that the size ofthe jet-holes should be adjusted with reference to the quality orpressure or supply of the gas being used, and it is often foundexpedient in sending stoves to a market where the exact gas conditionsare not fully known to make the jet-holes small and to enlarge them tosuit the ascertained conditions. The form of burners shown permits ofthe ready opening of the burners and the exposure of the notches, sothat they may be enlarged by the simple operation of filing, which canbe done in most any situation where such stoves are likely to beemployed, and this capacity for treatment holds good, notwithstandingthe burner may have the two series of j et-holes C and H.

The open central tube may be embodied as desired, and if the tube beemployed, as will be found preferable, it may be preferred to embody thejet-holes O to form a sub-burner to heat the gas within the chamber ofthe burner, as in my patent, No. 401,783. If such central tube andjet-holes be employed, as in the exemplification, then the system ofconstruction set forth permits of the construction and subsequenttreatment of the subburner jet-holes O with the same facility as theother jet-holes.

I claim as my invention In a gas-burner, the combination, substantiallyas set forth, of two concentric burner parts joined to and adapted forangular adjustment with reference to each other, a supporting-armrigidly attached to one of said burner parts, and a supply-pipe attachedto the other of said burner parts.
